As others have said on this thread generally leftists have less money, and the establishment will always try and reduce the amount of money that independent creatives who could be leftist have access to. Notably in Britain scrapping the UK Film Council (which was certainly not inherently leftist but did fund various films with good messages such as Threads) was one of the first things David Cameron did when he became PM - and then Boris Johnson went on a tirade about Britain not putting out any art worth watching, super cool!
